The Department of Physics had the privilege of hosting a distinguished guest lecture by Prof. Dr. Bilal Masud, Ex-Director of the Centre for High Energy Physics at the University of the Punjab, on Friday, January 24, 2025.
Topic:
Introduction to Quantum Electrodynamics
Prof. Dr. Bilal Masud delivered a comprehensive and intellectually stimulating lecture introducing the foundations of Quantum Electrodynamics (QED) — the quantum field theory describing the interaction between light and matter. The session provided students with conceptual clarity on the unification of quantum mechanics and special relativity in explaining electromagnetic interactions.
Key highlights of the lecture included:
-
Fundamental principles of quantum field theory
-
Interaction of charged particles through photon exchange
-
Feynman diagrams and perturbation theory
-
Renormalization and its significance in QED
-
Experimental validations and precision tests of QED
Prof. Masud emphasized the elegance and predictive power of QED, describing it as one of the most successful theories in modern physics. He also encouraged students to build strong mathematical foundations to pursue advanced studies in theoretical and particle physics.
The interactive discussion session allowed students to engage deeply with advanced concepts, ask research-oriented questions, and explore future academic pathways in high-energy physics.
The Department of Physics expresses its sincere appreciation to Prof. Dr. Bilal Masud for sharing his profound knowledge and inspiring students toward excellence in theoretical physics and fundamental research.
